第一次世界大战期间,各参战国都竭尽全力生产大量的枪支供前方使用。但当时用来造枪的钢材强度很差,一支枪往往用不多久枪膛就磨损报废了。英国科学家亨利·布里尔为了提高钢的强度,制造出适应前方使用的枪支,他在熔化的钢水中加入了一定数量的铬,但结果并未达到预期效果。于是,这炉炼出的钢块象往常一样,被扔进了废铁堆。一个夏季过去了,布里尔惊奇地发现,在一大堆锈迹斑斑的废铁中,唯有一块亮晶晶的极为醒目。他连忙 During the First World War, all participating countries made every effort to produce a large quantity of firearms for the front. However, the strength of the steel used to make the gun at the time was so poor that one gun was often worn out and worn out by the gun. In order to increase the strength of the steel, British scientist Henry Brill made a gun that fits forward, adding a certain amount of chromium to the molten steel, but the result was not as expected. As a result, the steel blocks from this furnace were thrown into the scrap pile as usual. A summer passed, Brill surprised to find that in a lot of rusty scrap iron, only a sparkling eye-catching. He quickly
